85-500: On July 7, 2017, an Airbus A320-211 operating as Air Canada Flight 759 was nearly involved in an accident at San Francisco International Airport in San Mateo County , California , United States . The flight, which originated at Toronto Pearson International Airport , had been cleared by air traffic control to land on runway 28R and was on final approach to land on that runway; however, instead of lining up with

170-678: A 3.5% fuel burn reduction on flights over 2,800 km (1,500 nmi; 1,700 mi), saving approximately US$ 220,000 and 700 t of CO 2 per aircraft per year. The 2.5 metres (8 ft 2 in) tall wingtip devices are manufactured by Korean Air Aerospace Division. In December 2011, Airbus filed suit in the western district of Texas over Aviation Partners ' claims of infringement of its patents on winglet design and construction which were granted in 1993. Airbus' lawsuit seeks to reject responsibility to pay royalties to Aviation Partners for using its designs, despite work performed together with both parties to develop advanced winglets for

255-817: A 60 monthly global production rate by mid-2019, the Tianjin line delivered 51 in 2016 and it could assemble six per month from four as it starts producing A320neos in 2017; 147 Airbus were delivered in 2016 in China, 20% of its production, mostly A320-family, a 47% market share as the country should become the world's largest market ahead of the US before 2027. In June 2018, along a larger and modernised delivery centre, Airbus inaugurated its fourth Hamburg production line, with two seven-axis robots to drill 80% of fuselage upper side holes, autonomous mobile tooling platforms and following Design Thinking principles. By January 2019, Mobile

340-577: A 95- to 125-seat aircraft project. The programme was called the AE31X , and covered the 95-seat AE316 and 115- to 125-seat AE317. The former would have had an overall length of 31.3 m (102 ft 8 in), while the AE317 was longer by 3.2 m (10 ft 6 in), at 34.5 m (113 ft 2 in). The engines were to be two Rolls-Royce BR715s, CFM56-9s, or the Pratt & Whitney PW6000 ; with

425-494: A company based in Wichita , Kansas , USA. Two aircraft were used in the flight test evaluation campaign – the prototype A320, which had been retained by Airbus for testing, and a new build aircraft which was fitted with both types of winglets before it was delivered to JetBlue . Despite the anticipated efficiency gains and development work, Airbus announced that those winglets would not be offered to customers, claiming that

510-551: A design called the HS.134 "Airbus" in 1965, an evolution of the HS.121 (formerly DH.121) Trident , which shared much of the general arrangement of the later JET3 study design. The name "Airbus" at the time referred to a BEA requirement, rather than to the later international programme. In June 1977 a new Joint European Transport (JET) programme was set up, established by British Aerospace (BAe), Aerospatiale , Dornier and Fokker . It

595-512: A dispute between the French, who claimed the move would incur $ 150 million (€135 million) in unnecessary expenditures associated with the new plant, and the Germans, who argued that it would be more productive for Airbus in the long run. The second production line was located at Hamburg , which would also subsequently produce the smaller Airbus A319 and A318. For the first time, Airbus entered

680-437: A full glass cockpit, rather than the hybrid versions found in previous airliners. It is also equipped with an Electronic Flight Instrument System (EFIS) with side-stick controllers. The A320 has an Electronic Centralised Aircraft Monitor (ECAM) to give the flight crew information about all of the systems on the aircraft. The only analogue instruments were the radio-magnetic indicator and brake pressure indicator. Since 2003,

765-715: A fuselage diameter of "the Boeing 707 and 727, or do something better" and settled on a wider cross-section with a 3.7 m (12 ft 2 in) internal width, compared to Boeing's 3.45 m (11 ft 4 in). Although heavier, this allowed the A320 to compete more effectively with the 737. The A320 wing went through several design stages, eventually measuring 33.91 m (111 ft 3 in). The UK, France and West Germany wanted responsibility over final assembly and its associated work, known as "work-share arguments". The Germans requested an increased work-share of 40%, while

850-453: A new air purifier with filters and a catalytic converter , removing unpleasant smells from the air before it is pumped into the cabin, as well as LEDs for mood lighting and a new passenger service unit (PSU). Offering 10% more overhead bin volume, more shoulder room, a weight reduction, a new intercom and in-flight entertainment system, noise reduction and slimmer PSU, the enhanced cabin can be retrofitted. The flight crew controls

935-500: A passenger on AC759, wrote a letter to Air Canada a week after the incident requesting their cooperation with the investigation. Preliminary NTSB investigation results from flight data recorder telemetry, released on August 2, 2017, indicate that AC759 reached a minimum altitude of 59 feet (18 m) above ground level, comparable to the 55 ft 10 in (17.02 m) tail height of a Boeing 787-9 , two of which were on Taxiway C. The cockpit voice recorder had been overwritten before

1020-455: A production rate of 63 aircraft per month by 2021, which would result in the 10,000th delivery occurring early that year. Due to the impact of the COVID-19 pandemic on aviation , demand for new jets was reduced in 2020 and Airbus cut its monthly production from 60 to 40 A320s. In October 2020, the 500th A320 built in Tianjin, an A320neo, was delivered to China Southern , twelve years after

1105-414: A retractable tricycle landing gear and powered by two wing pylon-mounted turbofan engines . After the oil price rises of the 1970s , Airbus needed to minimise the trip fuel costs of the A320. To that end, it adopted composite primary structures for the empennage with a conventional tail configuration, centre-of-gravity control using fuel, a glass cockpit ( EFIS ) with side-stick controllers and

1190-536: A shorter-range twinjet rather than a longer-range quadjet wanted by the West Germans, particularly Lufthansa . However, works proceeded, and the German carrier would eventually order the twinjet. In February 1981 the project was re-designated A320, with efforts focused on the blueprint formerly designated SA2. During the year, Airbus worked with Delta Air Lines on a 150-seat aircraft envisioned and required by

1275-596: A six-abreast economy cross-section and came with either CFM56 or IAE V2500 turbofan engines, except the CFM56/ PW6000 powered A318. The family pioneered the use of digital fly-by-wire and side-stick flight controls in airliners. Variants offer maximum take-off weights from 68 to 93.5 tonnes (150,000 to 206,000 lb), to cover a 5,740–6,940 kilometres ; 3,570–4,320 miles (3,100–3,750 nmi) range . The 31.4 m (103 ft) long A318 typically accommodates 107 to 132 passengers. The 124-156 seat A319

1360-460: A two-crew flight deck. Airbus claimed the 737-300 burns 35% more fuel and has a 16% higher operating cost per seat than the V2500 -powered A320. A 150-seat A320 burns 11,608 kg (25,591 lb) of jet fuel over 2,151 nmi (3,984 km; 2,475 mi) (between Los Angeles and New York City), or 2.43 L/100 km (97 mpg ‑US ) per seat with a 0.8 kg/L fuel. Its wing

1445-500: A wingspan of 31.0 m (101 ft 8 in) and a flight deck similar to that of the A320 family. Costing $ 2 billion (€1.85 billion) to develop, aircraft production was to take place in China. Simultaneously, Airbus was developing the Airbus A318. In early 1998, Airbus revealed that it was designing a 100-seat aircraft based on the A320. The AE31X project was terminated by September 1998, and Airbus officially announced

1530-622: Is 33.8 m (111 ft) long. The A320 is 37.6 m (123 ft) long and can accommodate 150 to 186 passengers. The 44.5 m (146 ft) A321 offers 185 to 230 seats. The Airbus Corporate Jets are modified business jet versions of the standard commercial variants. In December 2010, Airbus announced the re-engined A320neo ( new engine option ), which entered service with Lufthansa in January 2016. With more efficient turbofans and improvements including sharklets , it offers up to 15% better fuel economy . The previous A320 generation

1615-467: Is closed" and replacing them with instrument approaches , either ILS or satellite-based , and requiring two air traffic controllers in the control tower "until the late-night arrival rush is over". Airbus A320 family#A320 The Airbus A320 family is a series of narrow-body airliners developed and produced by Airbus . The A320 was launched in March 1984, first flew on 22 February 1987, and

1700-459: Is long and thin, offering better aerodynamic efficiency because of the higher aspect ratio than the competing 737 and MD-80. The Airbus A320 family are low-wing cantilever monoplanes with a conventional empennage with a single vertical stabiliser and rudder . Its wing sweep is 25 degrees. Compared to other airliners of the same class, the A320 features a wider single-aisle cabin of 3.95 metres (156 in) outside diameter, compared to

1785-588: Is more reactive than proactive. The report faults Air Canada for reporting too late and erasing the voice record, but notes that the NTSB only requires notification when an aircraft lands or departs on a taxiway, or when a collision is avoided after a runway incursion , and neither happened. It also dismisses a comparable taxiway mishap in Seattle-Tacoma by Alaska Airlines (Flight 27) in December 2015, that

1870-692: Is now called A320ceo ( current engine option ). American Airlines is the largest A320 operator with 479 aircraft in its fleet, while IndiGo is the largest customer with 930 aircraft on order. In October 2019, the A320 family surpassed the Boeing 737 to become the highest-selling airliner. As of October 2024 , a total of 18,994 A320 family aircraft had been ordered and 11,707 delivered , of which 10,803 aircraft were in service with more than 350 operators. The global A320 fleet had completed more than 176 million flights over 328 million block hours since its entry into service. The A320ceo initially competed with

1955-538: Is simplifying its SFO approach charts and includes SFO-specific training in aircraft simulators, trains its staff to reduce expectation bias , and will retrofit new aircraft like the Airbus A220 and Boeing 737 Max with dual head-up displays to enhance situational awareness in low-visibility, high-risk approaches. The NTSB published their final report in September 2018; five recommendations were made. As

2040-632: The 737 Classic and the MD-80 , then their successors, the 737 Next Generation (737NG) and the MD-90 respectively, while the 737 MAX is Boeing's response to the A320neo. When Airbus designed the A300 during the late 1960s and early 1970s, it envisaged a broad family of airliners with which to compete against Boeing and Douglas (later McDonnell Douglas ), two established US aerospace manufacturers. From

2125-650: The EUROPLANE , a 180- to 200-seat aircraft. It was abandoned after intruding on A310 specifications. VFW-Fokker , Dornier and Hawker Siddeley worked on a number of 150-seat designs. The design within the JET study that was carried forward was the JET2 (163 passengers), which then became the Airbus S.A1/2/3 series (Single Aisle), before settling on the A320 name for its launch in 1984. Previously, Hawker Siddeley had produced

2210-571: The National Transportation Safety Board (NTSB) determined that the Air Canada airplane descended to 59 feet (18 m) above the ground before it began its climb, and that it missed colliding with one of the aircraft on the taxiway by 14 feet (4.3 m). The NTSB determined the probable cause was the Air Canada flight crew's confusion of the runway with the parallel taxiway, with contributing causes including

2295-530: The V2500Select (One) . In 2006, Airbus tested three styles of winglets intended to counteract the wing's lift-induced drag and wingtip vortices more effectively than the previous wingtip fence . The first design type to be tested was developed by Airbus and based on work done by the AWIATOR programme. The second type of winglet incorporated a more blended design and was designed by Winglet Technology,

2380-646: The bond market , through which it raised $ 480 million (€475 million) to finance development costs. An additional $ 180 million (€175 million) was borrowed from the European Investment Bank and private investors. The maiden flight of the Airbus A321 came on 11 March 1993, when the prototype , registration F-WWIA, flew with IAE V2500 engines; the second prototype, equipped with CFM56-5B turbofans, flew in May. Lufthansa and Alitalia were

2465-479: The dark cockpit (where an indicator is off when its system is running; useful for drawing attention to dysfunctions when an indicator is lit) from the A310, the first widebody designed to be operated without a flight engineer and influenced by Bernard Ziegler , first Airbus CEO Henri Ziegler 's son. The A320 is the world's first airliner with digital fly-by-wire (FBW) flight control system : input commands through

2550-546: The side-stick are interpreted by flight control computers and transmitted to flight control surfaces within the flight envelope protection ; in the 1980s the computer-controlled dynamic system of the Dassault Mirage 2000 fighter cross-fertilised the Airbus team which tested FBW on an A300 . At its introduction, fly-by-wire and flight envelope protection was a new experience for many pilots. Flight data recorder Too Many Requests If you report this error to

2635-400: The 3,588 nautical miles (6,645 km; 4,129 mi) great circle route to Winnipeg , Manitoba from Hamburg in 9 hours and 5 minutes. The A319 has proven popular with low-cost airlines such as EasyJet , which purchased 172 of them. The A318 was born out of mid-1990 studies between Aviation Industry Corporation of China (AVIC), Singapore Technologies Aerospace , Alenia and Airbus on

2720-496: The 3.8 m (148 in) of the Boeing 737 or 757 , and larger overhead bins. Its cargo hold can accommodate unit load device containers. The A320 airframe includes composite materials and aluminium alloys to save weight and reduce the total number of parts to decrease the maintenance costs. Its tail assembly is made almost entirely of such composites by CASA, which also builds the elevators , main landing gear doors, and rear fuselage parts. The A320 flight deck features

2805-543: The A318 at that year's Farnborough Airshow. The aircraft was the smallest in Airbus's product range, and was developed coincidentally at the same time as the largest commercial aircraft in history, the Airbus A380 . First called A319M5 in as early as March 1995, it was shorter by 0.79-metre (2 ft 7 in) ahead of the wing and 1.6 metres (5 ft 3 in) behind. These cuts reduced passenger capacity from 124 on

2890-456: The A319 to 107 passengers in a two-class layout. Range was 5,700 kilometres (3,100 nmi; 3,500 mi), or 5,950 kilometres (3,210 nmi; 3,700 mi) with upcoming Sharklets . The 107-seater was launched on 26 April 1999 with the options and orders count at 109 aircraft. After three years of design, the maiden flight took place at Hamburg on 15 January 2002. Tests on the lead engine,

2975-527: The A320 has featured liquid crystal display (LCD) units on the flight deck instead of the original cathode-ray tube (CRT) displays. These include both main displays and the backup artificial horizon , which also previously had an analogue display. Airbus offers an avionics upgrade for older A320 aircraft, the In-Service Enhancement Package, to keep them updated. Digital head-up displays are also available. The A320 retained

3060-563: The A320 overall. The length increase required enlarged overwing exits, which were repositioned in front of and behind the wings. The centre fuselage and undercarriage were reinforced to accommodate an increase in maximum takeoff weight of 9,600 kg (21,200 lb), for a total of 83,000 kg (183,000 lb). Final assembly for the A321 would be, as a first for any Airbus, carried out in Germany (then West Germany). This came after

3145-408: The A320 was to be named A30X . In 2007, Airbus North America President Barry Eccleston stated that the earliest the aircraft could have been available was 2017. In January 2010, John Leahy , Airbus's chief operating officer-customers, stated that an all-new single-aisle aircraft was unlikely to be constructed before 2024 or 2025. The Airbus A320 family are narrow-body (single-aisle) aircraft with

3230-539: The A320 was to be supplied by two CFM56-5-A1s rated at 111 kN (25,000 pounds-force). It was the only engine available until the arrival of the IAE V2500 , offered by International Aero Engines , a group composed of Rolls-Royce plc , Pratt & Whitney , Japanese Aero Engine Corporation , Fiat and MTU . The first V2500 variant, the V2500-A1, has a thrust output of 110  kN (25,000 pounds-force ), hence

3315-636: The Air Canada Pilots Association. The Federal Aviation Administration (FAA) received six recommendations: identifying approaches requiring an unusual manual frequency input; displaying it noticeably on aeronautical charts ; reviewing NOTAMs to prioritize and present relevant information; requiring aircraft landing in B or C airspace to alert pilots when not aligned with a runway; modifying airports to alert on collision risks and clearly showing closed runways, as construction lighting on 28L looked like ramp lighting . Air Canada

3400-596: The Airbus A320neo. The first sharklet-equipped Airbus A320 was delivered to Indonesia AirAsia on 21 December 2012, offering a 450 kg (990 lb) payload and 100 nmi (190 km; 120 mi) range increases over the original aircraft specifications. In 2007, Airbus introduced a new enhanced, quieter cabin with better luggage storage and a more modern look and feel, and a new galley that reduced weight, increased revenue space and improved ergonomics and design for food hygiene and recycling. It offered

3485-701: The Airbus Americas factory in Mobile, Alabama . Airbus produced a total of 42 A320s per month in 2015, and expected to increase to 50 per month in 2017. Production of parts takes place in a large number of countries around the world. For example, the centre fuselage is made in Hamburg, Germany; the horizontal stabiliser is produced in Getafe, Spain; and the rudder is produced in Harbin, China. As Airbus targets

3570-503: The British wanted the major responsibilities to be swapped around to give partners production and research and development experience. In the end, British work-share was increased from that of the two previous Airbuses. France was willing to commit to launch aid, or subsidies, while the Germans were more cautious. The UK government was unwilling to provide funding for the tooling, requested by BAe and estimated at £ 250 million; it

3655-471: The MTOW of 53.3 t (118,000 lb) for the smaller version and 58 t (128,000 lb) for the AE317, the thrust requirement were 77.9–84.6 kN (17,500–19,000 lbf) and 84.6–91.2 kN (19,000–20,500 lbf), respectively. Range was settled at 5,200 km (2,800 nmi; 3,200 mi) and 5,800 km (3,100 nmi; 3,600 mi) for the high gross weights of both variants. Both share

3740-611: The NTSB to re-evaluate those reporting requirements. The United States National Transportation Safety Board (NTSB) was informed of the incident on July 9, and took the lead on the investigation, with assistance from the Federal Aviation Administration (FAA). The Transportation Safety Board of Canada (TSB) served as a facilitator to convey information between Air Canada and the NTSB. TSB released preliminary information from Occurrence No. A17F0159 on July 11, 2017. NTSB assigned identification number DCA17IA148 to

3825-519: The PW6000, revealed worse-than-expected fuel consumption. Consequently, Pratt & Whitney abandoned the five-stage high-pressure compressor (HPC) for the MTU-designed six-stage HPC. The 129 order book for the A318 shrunk to 80 largely because of switches to other A320 family members. After 17 months of flight certification, during which 850 hours and 350 flights were accumulated, JAA certification

3910-422: The airline. The A320 would carry 150 passengers over 2,850 or 1,860 nmi (5,280 or 3,440 km; 3,280 or 2,140 mi) using fuel from wing fuel tanks only. The -200 had the centre tank activated, increasing fuel capacity from 15,590 to 23,430 L (3,429 to 5,154 imp gal). They would measure 36.04 and 39.24 m (118 ft 3 in and 128 ft 9 in), respectively. Airbus considered

3995-421: The cabin through touchscreen displays. The A320neo ( neo for new engine option ) is a development launched on 1 December 2010, making its first flight on 25 September 2014 and introduced by Lufthansa on 25 January 2016. Re-engined with CFM International LEAP -1A or Pratt & Whitney PW1000G engines and with large sharklets, it was designed to be 15% more fuel efficient. Its three variants are based on

4080-553: The consortium focused on its bigger siblings. After healthy sales of the A320/A321, Airbus focused once more on what was then known as the A320M-7 , meaning A320 minus seven fuselage frames . It would provide direct competition for the 737-300 / -700 . The shrink was achieved through the removal of four fuselage frames fore and three aft of the wing, cutting the overall length by 3.73 metres (12 ft 3 in). Consequently,

4165-521: The crew's failure to use the instrument landing system (ILS), as well as pilot fatigue . A retired pilot stated the runway confusion that almost happened "probably came close to the greatest aviation disaster in history" as five airplanes and potentially over 1,000 passengers were at imminent risk of a disaster greater than the Tenerife airport disaster . At 11:46 p.m. local time, Air Canada Flight 759, carrying 135 passengers and 5 crew members,

4250-535: The final assembly line start in 2008. In 2006, Airbus started the A320 Enhanced (A320E) programme as a series of improvements targeting a 4–5% efficiency gain, with large winglets (2%), aerodynamic refinements (1%), weight savings and a new aircraft cabin . Engine improvements that reduced fuel consumption by 1% were made to the A320 in 2007 with the CFM56 Tech Insertion and in 2008 with

4335-486: The first to order the stretched Airbuses, with 20 and 40 aircraft, respectively. The first of Lufthansa's V2500-A5-powered A321s arrived on 27 January 1994, while Alitalia received its first CFM56-5B-powered aircraft on 22 March. The A319 was the following derivative of the baseline A320. The design was a "shrink", with its origins in the 130- to 140-seat SA1, part of the Single-Aisle studies, which had been shelved as

4420-595: The flight crew, in the flight management system (FMS) visual approach; and pilot fatigue . The crew's body clock was at the Toronto 03:00 Eastern Time : the first officer had no significant rest for 12 h, and the captain for 19 h – he would not have been able to fly under US pilot fatigue rules. Transport Canada planned to bring its pilot rest rules in line with international standards later in 2018. New regulations were announced in December 2018, closer to international standards but criticized as substandard by

4505-601: The following day. The certification programme took 350 airborne hours involving two aircraft. Certification for the CFM56-5B6/2-equipped variant was granted in April 1996, and qualification for the V2524-A5 started the following month. Delivery of the first A319, to Swissair , occurred on 25 April 1996; it entered service by month's end. In January 1997, an A319 broke a record during a delivery flight by flying

4590-461: The go-around order. Afterwards, the pilot of UA001 radioed the tower saying, "Air Canada flew directly over us," and the air traffic controller responded, "Yeah, I saw that, guys." During the first approach, AC759 flew for 1 ⁄ 4 mile (400 m) over Taxiway C, descended to an altitude as low as 81 feet (25 m) and approached as close as 29 feet (8.8 m) laterally to the four airplanes waiting on Taxiway C before being ordered to abort

4675-522: The incident. A retired pilot stated that SFO requires "precision flying" as the two runways (28R and 28L) are laterally separated by 750 feet (230 m), and Taxiway C is separated from 28R by less than 500 feet (150 m). Other pilots pointed out that some airlines require all aircraft to use the instrument landing system (ILS) regardless of weather or visibility, which would have led the crew to realize that they were not lined up with runway 28R. Dave Jones , then California Insurance Commissioner and

4760-508: The investigation was launched, as C-FKCK flew three more flights on July 8 before the NTSB was informed of the near-miss on July 9. In a September 25, 2018, board meeting, the NTSB cited as probable cause the pilots mistaking taxiway C for runway 28R due to overlooking the closure of runway 28L in the NOTAM report. Contributing factors included not taking advantage of the ILS, which was not in use by

4845-447: The landing. According to the flight data recorder , the pilots advanced the thrust levers when the airplane was 85 feet (26 m) above the ground. The airplane descended as low as 59 feet (18 m), approximately 2.5 seconds after the thrust levers had been advanced. Following a reconstruction of events, one pilot not involved in the incident noted that had the crew waited five more seconds before pulling up, it would have collided with

4930-524: The local controller's ASSC display for twelve seconds, between 11:55:52 and 11:56:04 p.m. local time (from shortly after the AC759 pilot asked for confirmation that 28R was clear, to the time the UA001 pilot noted that AC759 was lined up for Taxiway C), as AC759 was too far off-course from 28R. AC759 completed its go-around and landed without incident after the second approach. A single air traffic controller

5015-444: The long-range Airbus A310 . Airbus then focused its efforts on the single-aisle market, which was dominated by the 737 and McDonnell Douglas DC-9 . Plans from a number of European aircraft manufacturers called for a successor to the relatively successful BAC One-Eleven , and to replace the 737-200 and DC-9. Germany's MBB ( Messerschmitt-Bölkow-Blohm ), British Aircraft Corporation , Sweden's Saab and Spain's CASA worked on

5100-611: The moment of formation, Airbus had begun studies into derivatives of the Airbus A300B in support of this long-term goal. Prior to the service introduction of the first Airbus airliners, engineers within Airbus had identified nine possible variations of the A300 known as A300B1 to B9. A 10th variation, conceived in 1973, later the first to be constructed, was designated the A300B10. It was a smaller aircraft which would be developed into

5185-557: The most significant orders occurred when Northwest Airlines placed an order for 100 A320s in October 1986, powered by CFM56 engines, later confirmed at the 1990 Farnborough Airshow . During A320 development, Airbus considered propfan technology, which was backed by Lufthansa . At the time unproven, the technology essentially consisted of a fan placed outside the engine nacelle , offering turbofan speeds and turboprop economics; ultimately, Airbus stuck with turbofans .

5270-737: The name. It is 4% more efficient than the CFM56, with cruise thrust-specific fuel consumption for the -A5 at 16.3 and 16.9 g/kN/s (0.58 and 0.60 lb/lbf/h) for the CFM56-5A1. In the presence of then- French Prime Minister Jacques Chirac and the Prince and Princess of Wales , the first A320 was rolled out of the final assembly line at Toulouse on 14 February 1987 and made its maiden flight on 22 February in 3 hours and 23 minutes. The flight test programme took 1,200 hours over 530 flights. European Joint Aviation Authorities (JAA) certification

5355-403: The new model from 22 May 1992, with the actual launch of the $ 275 million (€250 million) programme occurring on 10 June 1993; the A319's first customer was ILFC , which signed for six aircraft. On 23 March 1995, the first A319 underwent final assembly at Airbus' German plant in Hamburg, where A321s were also assembled. It was rolled out on 24 August 1995, with the maiden flight taking place

5440-544: The number of overwing exits was reduced from four to two. The bulk-cargo door was replaced by an aft container door, which can take in reduced height LD3-45 containers . Minor software changes were made to accommodate the different handling characteristics; otherwise the aircraft was largely unchanged. Power is provided by the CFM56-5A, CFM56-5B, or V2500-A5, derated to 98  kN (22,000 lbf), with option for 105 kN (24,000 lbf) thrust. Airbus began offering

5525-435: The parallel taxiway C, even though runways and taxiways are lit with different colors and intensities. Preliminary post-event investigation results noted that Runway 28R and Taxiway C were lit on default settings (in different colors), and the automatic terminal information service broadcast information was current and advised that 28L was closed and unlit. According to preliminary Transportation Board investigation results, as

5610-425: The pilots were slow to report the incident, the airplane had made another flight and the cockpit voice recording was recorded over. The NTSB has stated that it wants faster incident reporting and considers recommending capturing the last 25 hours, an increase from two hours. A former NTSB investigator observed deficiencies in the investigation, criticizing the board for avoiding introspection and indicating that it

5695-466: The previous A319, A320 and A321. Airbus received 6,031 orders by March 2018 and delivered 318 by May 2018. The original family was renamed A320ceo, for current engine option . As of July 2024, IndiGo has 173 Airbus A320neos under service, making it the largest operator of this type of aircraft. In 2006, Airbus was studying a future replacement for the A320 series, tentatively dubbed as NSR or "New Short-Range aircraft". The follow-on aircraft to replace

5780-521: The runway, the AC759 pilot asked the tower if he was clear to land on 28R, to which the air traffic controller responded at 11:55:56 p.m., "There's no one on 28R but you," when AC759 was approximately 0.3 miles (500 m) from the runway threshold. The AC759 pilots "did not recall seeing aircraft on Taxiway C, but something did not look right to them" according to a post-incident interview summary. The crew of Philippine Airlines 115 (PR115) turned on their landing lights to alert AC759 they were lined up on

5865-405: The runway, the aircraft had lined up with the parallel taxiway , on which four fully loaded and fueled passenger airplanes were stopped awaiting takeoff clearance. The flight crew initiated a go-around prior to landing, after which it landed on 28R without further incident. The aircraft on the taxiway departed for their intended destinations without further incident. The subsequent investigation by

5950-466: The taxiway. The pilot of United Airlines 1 (UA001), the first in line for takeoff, interrupted the radio traffic at 11:56:01 p.m. and asked "Where is this guy going? He's on the taxiway." The air traffic controller then ordered AC759 to abort the landing at 11:56:10 p.m. After AC759 acknowledged the go-around, the air traffic controller stated, "It looks like you were lined up for Charlie [Taxiway C] there." AC759 had already started to climb before

6035-591: The third airplane (UAL 863) on the taxiway. There was also less than 10 to 20 feet (3 to 6 m) separation between the bottom of the Air Canada aircraft and the tail of the Philippine Airlines A340 . SFO was the first airport in the United States to install an Airport Surface Surveillance Capability (ASSC) system, which should have alerted the tower of a potential conflict between runway and taxiway movements. AC759 disappeared from

6120-418: The weather was clear, the pilots of AC759 were not required to utilize the instrument landing system and relied instead on a visual approach, as typical for the prevailing conditions. Taxiway C contained four airplanes, three from United Airlines and one from Philippine Airlines , queueing for takeoff. At 11:55:46 p.m. local time, upon spotting aircraft lights approximately 0.7 miles (1.1 km) from

6205-492: The weight of the modifications required negated any aerodynamic benefits. On 17 December 2008, Airbus announced it was to begin flight testing an existing blended winglet design developed by Aviation Partners Inc. as part of an A320 modernisation programme using the A320 prototype. Airbus launched the sharklet blended winglets during the November 2009 Dubai Airshow . Installation adds 200 kg (440 lb) but offers

6290-635: Was awarded on 26 February 1988. The first A320 was delivered to Air France on 28 March, and began commercial service on 8 April with a flight between Paris and Berlin via Düsseldorf . In 1988, the clean-sheet aircraft program cost was 5.486 billion French francs . The first derivative of the A320 was the Airbus A321 , also known as the Stretched A320 , A320-500 and A325 . Its launch came on 24 November 1988 after commitments for 183 aircraft from 10 customers were secured. The aircraft

6375-470: Was based at the then BAe (formerly Vickers ) site in Weybridge , Surrey , UK. Although the members were all of Airbus' partners, they regarded the project as a separate collaboration from Airbus. This project was considered the forerunner of Airbus A320, encompassing the 130- to 188-seat market, powered by two CFM56s . It would have a cruise speed of Mach 0.84 (faster than the Boeing 737). The programme

6460-407: Was cleared to land on Runway 28R. The adjacent Runway 28L had been closed at 10 p.m. local time and its lights were off, except for a 20.5-foot-wide (6.2 m) lighted flashing "X" at the eastern runway threshold. The captain was flying the aircraft and the first officer was monitoring. The two pilots of AC759 acknowledged that they mistook runway 28R for 28L and therefore lined up for landing on

6545-511: Was introduced in April 1988 by Air France . The first member of the family was followed by the stretched A321 (first delivered in January 1994), the shorter A319 (April 1996), and the even shorter A318 (July 2003). Final assembly takes place in Toulouse in France; Hamburg in Germany; Tianjin in China since 2009; and Mobile, Alabama in the United States since April 2016. The twinjet has

6630-431: Was its first customer to sign a "letter of intent" for 25 A320s and options for 25 more at the 1981 Paris Air Show . In October 1983, British Caledonian placed seven firm orders, bringing total orders to more than 80. Cyprus Airways became the first customer to place an order for V2500-powered A320s in November 1984, followed by Pan Am with 16 firm orders and 34 options in January 1985, and then Inex Adria . One of

6715-537: Was later transferred to Airbus, leading up to the creation of the Single-Aisle (SA) studies in 1980, led by former leader of the JET programme, Derek Brown. The group looked at three different variants, covering the 125- to 180-seat market, called SA1 , SA2 and SA3 . Although unaware at the time, the consortium was producing the blueprints for the A319, A320 and A321, respectively. The single-aisle programme created divisions within Airbus about whether to design

6800-456: Was monitoring ground and tower frequencies, which would typically be handled by two controllers. The aircraft flying AC759 that night was C-FKCK, an Airbus A320-200. The aircraft was 24.5 years old on the day of the incident, first flying in December 1992. The incident was not considered reportable under then-current federal regulations, but former NTSB chairman Jim Hall called it "the most significant near-miss we've had in this decade" and urged

6885-634: Was obtained for the CFM56-powered variant on 23 May 2003. On 22 July 2003, first delivery for launch customer Frontier Airlines occurred, entering service before the end of the month. The Toulouse Blagnac final assembly line builds A320s, whereas the Hamburg Finkenwerder final assembly line builds A318s, A319s, and A321s. The Airbus factory in Tianjin , China assembles A319s, A320s, and A321s; A320s and A321s are also assembled at

6970-441: Was outputting 4.5 A320s per month, raising to five by the end of the year. In September 2019, Airbus reached a milestone with the delivery of the 9000th A320-family aircraft, to Easyjet. In October 2019, Airbus inaugurated a highly automated fuselage structure assembly line for A320 Family aircraft in Hamburg, showcasing an evolution in Airbus' industrial production system. Production rates continue to rise, and Airbus aims to reach

7055-444: Was postponed for three years. On 1 March 1984, the British government and BAe agreed that £50 million would be paid, whether the A320 flew or not, while the rest would be paid as a levy on each aircraft sold. In 1984, the program cost was then estimated at £2 billion ($ 2.8 billion) by Flight International, equivalent to £8 billion today. The programme was launched on 2 March 1984. At the time, Airbus had 96 orders. Air France

7140-669: Was still in the preliminary investigation stage at the time (NTSB assigned identification number DCA16IA036 to the incident). The recommendation to improve the NOTAM system led to an ICAO initiative to reform it. Robert Sumwalt , Chairman of the NTSB, described NOTAMs as "a bunch of garbage that nobody pays any attention to". Following the incident, in early August the Federal Aviation Administration modified nighttime landing procedures at SFO, forbidding visual approaches at night "when an adjacent parallel runway

7225-448: Was to be a minimally changed derivative, apart from minor wing modifications and the fuselage stretch itself. The wing would incorporate double-slotted flaps and minor trailing edge modifications, increasing wing area from 124 m (1,330 sq ft) to 128 m (1,380 sq ft). The fuselage was lengthened by four plugs (two ahead and two behind the wings), making the A321 6.94 metres (22 ft 9 in) longer than
